THE ENVIRONMENTAL EFFECT OF THE MIGRATION AND TRANSFORMATION OF FLUORINE IN THE WATER-SOIL-PLANT SYSTEM FOR THE AREA OF LONG-TERM AGRICULTURAL IRRIGATION WITH HIGH F WATER |
|
| Abstract: | he environmental effect of the migration and transformation of fluorine in thewater-soil-plant system for the area of long-term agricultural irrigation with high F wateris discussed on the basis of the characteristics of F accumulation and distribution in thesoils irrigated with high F water, the experimental results of F sorption isotherm and soilcolumn as well as F contents in the grains of crops (wheat and corn). The samples (soiland crops) were collected from Cangxian, Hebei. The prevention countermeasures of fluorine environment deterioration are suggested. |
| Keywords: | high F water irrigation water-soil-plant system migration and transformation of fluorine environmental effect prevention countermeasures |
